2014-01-14Merge branch 'skb_checksum_help'David S. Miller
Paul Durrant says: ==================== make skb_checksum_setup generally available Both xen-netfront and xen-netback need to be able to set up the partial checksum offset of an skb and may also need to recalculate the pseudo- header checksum in the process. This functionality is currently private and duplicated between the two drivers. Patch #1 of this series moves the implementation into the core network code as there is nothing xen-specific about it and it is potentially useful to any network driver. Patch #2 removes the private implementation from netback. Patch #3 removes the private implementation from netfront. v2: - Put skb_checksum_setup in skbuff.c rather than dev.c - remove inline ==================== Signed-off-by: David S.

2014-01-14net: add skb_checksum_setupPaul Durrant
This patch adds a function to set up the partial checksum offset for IP packets (and optionally re-calculate the pseudo-header checksum) into the core network code. The implementation was previously private and duplicated between xen-netback and xen-netfront, however it is not xen-specific and is potentially useful to any network driver.

sh_eth_error() in case of a TX error tries to print a message using 2 dev_err() calls with the first string not finished by '\n', so that the resulting message would inevitably come out garbled, with something like "3net eth0: " inserted in the middle.

2014-01-14inet_diag: fix inet_diag_dump_icsk() to use correct state for timewait socketsNeal Cardwell
Fix inet_diag_dump_icsk() to reflect the fact that both TCP_TIME_WAIT and TCP_FIN_WAIT2 connections are represented by inet_timewait_sock (not just TIME_WAIT), and for such sockets the tw_substate field holds the real state, which can be either TCP_TIME_WAIT or TCP_FIN_WAIT2. This brings the inet_diag state-matching code in line with the field it uses to populate idiag_state. This is also analogous to the info exported in /proc/net/tcp, where get_tcp4_sock() exports sk->sk_state and get_timewait4_sock() exports tw->tw_substate. Before fixing this, (a) neither "ss -nemoi" nor "ss -nemoi state fin-wait-2" would return a socket in TCP_FIN_WAIT2; and (b) "ss -nemoi state time-wait" would also return sockets in state TCP_FIN_WAIT2. This is an old bug that predates 05dbc7b ("tcp/dccp: remove twchain").

Veaceslav Falico says: ==================== bonding: fix bond_3ad RCU usage While digging through bond_3ad.c I've found that the RCU usage there is just wrong - it's used as a kind of mutex/spinlock instead of RCU. v3->v4: remove useless goto and wrap __get_first_agg() in proper RCU. v2->v3: make bond_3ad_set_carrier() use RCU read lock for the whole function, so that all other functions will be protected by RCU as well. This way we can use _rcu variants everywhere. v1->v2: use generic primitives instead of _rcu ones cause we can hold RTNL lock without RCU one, which is still safe.

2014-01-14bonding: fix __get_active_agg() RCU logicVeaceslav Falico
Currently, the implementation is meaningless - once again, we take the slave structure and use it after we've exited RCU critical section.

Currently, the RCU read lock usage is just wrong - it gets the slave struct under RCU and continues to use it when RCU lock is released. However, it's still safe to do this cause we didn't need the rcu_read_lock() initially - all of the __get_first_agg() callers are either holding RCU read lock or the RTNL lock, so that we can't sync while in it.

2014-01-13net: gro: change GRO overflow strategyEric Dumazet
GRO layer has a limit of 8 flows being held in GRO list, for performance reason. When a packet comes for a flow not yet in the list, and list is full, we immediately give it to upper stacks, lowering aggregation performance. With TSO auto sizing and FQ packet scheduler, this situation happens more often. This patch changes strategy to simply evict the oldest flow of the list. This works better because of the nature of packet trains for which GRO is efficient. This also has the effect of lowering the GRO latency if many flows are competing. Tested : Used a 40Gbps NIC, with 4 RX queues, and 200 concurrent TCP_STREAM netperf. Before patch, aggregate rate is 11Gbps (while a single flow can reach 30Gbps) After patch, line rate is reached.
